As printed in the order notice (75 FR 57257, September 20, 2010). Your deposit today may differ: it is the rate the latest administrative review assigned to the exporter or producer on your invoice, which can be higher or lower. A company that has never been reviewed keeps the all-others rate. Check your supplier's current rate in Commerce's ACCESS case record before you price an order.
HTS numbers named in the scope
The notice lists these subheadings for convenience only. The written scope decides whether goods are covered, and goods entered under other HTS numbers can still be in scope.

Scope, from the order notice
Scope of the Orders
The scope of these orders includes certain chemically-bonded (resin
or pitch), magnesia carbon bricks with a magnesia component of at least
70 percent magnesia (``MgO'') by weight, regardless of the source of
raw materials for the MgO, with carbon levels ranging from trace
amounts to 30 percent by weight, regardless of enhancements (for
example, magnesia carbon bricks can be enhanced with coating, grinding,
tar impregnation or coking, high temperature heat treatments, anti-slip
treatments or metal casing) and regardless of whether or not
antioxidants are present (for example, antioxidants can be added to the
mix from trace amounts to 15 percent by weight as various metals, metal
alloys, and metal carbides). Certain magnesia carbon bricks that are
the subject of these orders are currently classifiable under
subheadings 6902.10.1000, 6902.10.5000, 6815.91.0000, 6815.99.2000 and
6815.99.4000 of the Harmonized Tariff Schedule of the United States
(``HTSUS''). While HTSUS subheadings are provided for convenience and
customs purposes, the written description is dispositive.

What A-201-837 means when you import
Cash deposit at entry. For every entry of goods in scope, CBP collects an estimated antidumping duty cash deposit at the rate assigned to the exporter or producer on the entry, on top of the Column 1 duty and any Chapter 99 trade-remedy lines.
Your supplier sets your rate. The same product from two plants in Mexico can deposit at different rates. Before you price the order, ask the supplier which legal entity will appear as exporter and as producer on the invoice.
Deposit now, final duty later. The deposit is not the final duty. The entry stays unliquidated until Commerce completes the administrative review for the period it was entered in. CBP then liquidates it at the rate that review sets and bills or refunds the difference with interest. AD/CVD entries can stay open for years, and the importer of record carries the difference. A review happens only if Commerce is asked for one in the order's anniversary month; if nobody asks, entries liquidate at the deposit rate.
Reimbursement certificate. Before liquidation, the importer files a certificate under 19 CFR 351.402(f)(2) stating whether the exporter has paid or reimbursed the antidumping duty. Without it, Commerce may presume reimbursement and deduct the duty a second time in the margin calculation. Brokers file it with the entry summary; make sure yours does.
Entry reporting. The AD/CVD case number goes on the 7501 line alongside the HTS number, and any Chapter 99 lines the goods carry are reported in the order CBP prescribes; the tariff updates tracker carries the current Chapter 99 sequence and the actions behind it.
Shipping from a third country doesn't change the origin. Goods finished, cut or packaged in a third country stay in scope if the notice's written scope covers them. A change of shipping origin is not a change of AD/CVD origin.
Estimating the stack. The tariff simulator returns the Column 1 rate and the Chapter 99 additional duties for an HTS number and origin. It does not include antidumping or countervailing deposits, so add the deposit at your supplier's current rate on top.
